General DescriptionThe MAX32660 evaluation system offers a compact devel-opment platform that provides access to all the fea-tures of the MAX32660 in a tiny, easy to use board. A MAX32625PICO-based debug adapter comes attached to the main board. It can be snapped free when program-ming is complete. The debug module supports an optional 10-pin Arm® Cortex® debug connector for DAPLink func-tionality. Combined measurements are 0.65in x 2.2in, while the main board alone measures 0.65in x 0.95in. External connections terminate in a dual-row header footprint com-patible with both thru-hole and SMT applications. This board provides a powerful processing subsystem in a very small space that can be easily integrated into a variety of applications.

Quick StartTo begin using the MAX32660 EV system, follow these steps:1) Use jumper JP1 to select desired target VDD.2) Connect the EVSYS board to the computer using the
included micro USB cable.3) Follow the instructions in the MAX32660 EV system
software user’s guide.
Detailed Description of Hardware (or Software)The MAX32660 EV system board is a compact breakout board designed to make developing with the MAX32660 quick and easy. In addition to making all the GPIOs accessible at 100mil pitch headers, it also includes key components such as decoupling capacitors and a crystal for the RTC. A pushbutton, LED, and debug adapter are also included. The two 100mil pitch headers are oriented in parallel so that this board can be inserted into a stan-dard solderless breadboard.
Power SupplyThe MAX32660 only needs a single supply between 1.7V and 3.6V to operate. The primary power input for this EV kit is the VDDIO pin at header J2 pin 9. Power can also be applied through the debug adapter (JP1 selects volt-age). The MAX32660 includes an internal LDO for the core supply. This LDO can be disabled so that a more efficient external regulator can be used. The EV kit pro-vides access to VCORE at header JH2 pin 8. VDDIO and VCORE are each decoupled with 1µF capacitors.
Programming and DebuggingThe MAX32660 EV kit integrates a MAX32625PICO- based debugger. The debugger provides power to the MAX32660 and is designed to be removed from the system when programming is finalized. It can be reat-tached by restoring the electrical connections between JH1 and JH2.

Console UARTUART1A Tx and Rx signals at port P0.10 and P0.11 are connected to the programming and debug header JH2 pins 2 and 3 through 1kΩ resistors. This provides a convenient way to communicate with a PC though the virtual serial port available in Maxim’s CMSIS-DAP debug adapter. The series resistors allow for these signals to be overdriven by other circuits without modifying the board.
PushbuttonA pushbutton is connected to GPIO P0.12 for general user input. It is connected through a series resistor to protect against contention if this I/O is being used for other purposes.
Indicator LEDA red LED is connected to GPIO P0.13 for general user indi-cation. It is connected with a MOSFET buffer so that it does not provide a significant load when used for other purposes.
ClockingThe IC operates from a system clock that can be selected from one of three on-chip oscillators from 8kHz to 96MHz. The external 32.768kHz crystal, Y2, provides the RTC with an accurate time base and is also used to calibrate the internal clock.
